The circadian clock is a fundamental timekeeping system that regulates rhythmic biological processes in response to environmental light–dark cycles. In mammals, core genes (CLOCK, BMAL1, PER, and CRY) orchestrate these rhythms through transcriptional–translational feedback loops, influencing various physiological functions, including bone remodeling. Bone homeostasis relies on the coordinated activities of osteoblasts, osteoclasts, osteocytes, with increasing evidence highlighting role regulation maintaining skeletal integrity. Disruptions are linked disorders such as osteoporosis. Posttranslational modifications (PTMs), phosphorylation, acetylation, ubiquitination, serve crucial regulators both mechanisms metabolism. However, specific PTMs integrating timing remodeling remains underexplored. This review examines intersection biology, elucidating their impact cell function homeostasis. Understanding interactions may uncover novel therapeutic targets for diseases associated disruptions.

Abstract Aim This study aimed to evaluate the impact of infusion timing time‐of‐day on clinical outcomes in patients with unresectable hepatocellular carcinoma (HCC) treated atezolizumab plus bevacizumab combination therapy. Methods A retrospective analysis was conducted using data from 751 HCC between September 2020 and April 2024. Patients were categorized into morning (AM; n = 351) afternoon (PM; 400) groups based time‐of‐day. Outcomes, including progression‐free survival (PFS), overall survival, objective response rate, disease control assessed Kaplan–Meier Cox regression analysis. Results The PFS significantly longer AM group (8.6 months, 95% CI 7.6–10.5) compared PM (6.0 5.4–7.0; p 0.006). In contrast, similar (AM: 24.7 months vs. PM: 21.4 months; 0.99). revealed that an independent favorable predictor (HR 1.23, 1.04–1.45). Additionally, demonstrated superior rate group, suggesting better tumor control. Conclusion Morning is associated improved rates patients, highlighting potential for optimizing treatment through circadian timing.
